Nintendo storm the top of the charts this week in what is by far the biggest ever launch of Pokemon games across one weekend in the UK.

‘Pokemon White Version’ becomes the 2nd fastest selling DS game ever (behind Professor Layton and Pandora’s Box), debuting at No1, 13,000 sales ahead of sister title ‘Pokemon Black Version’ which enters at No2. If you combine their sales together they become Nintendo’s third biggest ever UK launch (behind Wii Fit and Mario Kart Wii). Last week’s No1 ‘Killzone 3’ (-58%) falls down to No5, making way for both Pokemons as well as EA’s latest boxing title ‘Fight Night Champion’, new at No3, ahead of EA’s ‘Bulletstorm’ (-46%) which slips from No2 to No4. In the wake of half-term week, sales across all games in the Top 20 are down with ‘Black Ops’ (-54%) falling from No3 to No6 (its lowest ever chart position), while ‘Just Dance 2’ only falls 2 places to No7 with a respectable 20% drop in sales. EA and Nintendo occupy the remaining positions in the Top 10 with ‘FIFA 11’ (-40%) and ‘Dead Space 2’ (-59%) at No’s 8 and 9 and ‘Wii Party’ (-43%) at No10. There are not only new entries in the Top 10; two new PC titles also make the cut with THQ’s ‘Dawn of War II: Retribution’ launching at No17 and the MMORPG ‘Rift’ from newcomer Trion Worlds debuting at No19.
